Title: Video signal encoding method, its device, its program and its recording medium
Inventor: KOBAYASHI MITSURU
IPC: H04N19/91
Filed: 2001-01-30
Abstract: PROBLEM TO BE SOLVED: To provide a video signal encoder that reduces an encoded data amount without substantially deteriorating the quality of a reproduced video image. SOLUTION: Orthogonal transformation is applied to an input video signal, and the signal is then quantized. On the other hand, an analysis section 21 obtains features of each partial video image of the video signal, a distortion evaluation section 23 determines whether or not it is possible to revise an encoding parameter in a way that distortion caused by encoding is not made conspicuous based on a stored cross-reference with the features, and a coefficient control section 25 revises the encoding parameters, that is, performs increase/decrease in a value of a quantized orthogonal transform coefficients, deletion of the coefficients and revision of a quantization step size when the cross-reference exists. Variable length encoding is applied to the quantized orthogonal transform coefficients whose encoding parameter is revised.
